Annual Medicare Participation Announcement

Each year from mid-November through December 31, physicians and suppliers can decide if they want to participate in Medicare for the upcoming year. Medicare "participation" means you agree to accept assignment on all claims for all Medicare-covered services furnished to your patients. By accepting assignment, you agree to accept Medicare-allowed amounts as payment in full. You may not collect more from the patient than the applicable Medicare deductible and coinsurance or copayment.

Participating Physician or Supplier

  • Medicare pays the full Medicare Physician Fee Schedule allowed amount
  • Medicare pays you directly
  • Medicare forwards claim information to Medigap (Medicare supplement coverage) insurance

Non-Participating Physician or Supplier

  • Medicare pays 5% less than the Medicare Physician Fee Schedule allowed amount
  • You can't charge the patient more than the limiting charge, 115% of the Medicare Physician Fee Schedule amount for non-participating suppliers
  • You may accept assignment on a case-by-case basis
  • You have limited appeal rights
